Question
Transcribed Image Text:19. A consumer.research firm reports that the
95% confidence interval for the proportion
of consumers who prefer brand K tissue is
0.38 ± 0.04. If the research firm also conducts
a significance test of the null hypothesis
Ho:p = Po against the alternative Ha:p# Po,
which of the following statements must be
%3D
true?
(A) If po = 0.35, then the null hypothesis will
be rejected at the a = 0.05 significance
level.
(B) If po = 0.35, then the null hypothesis will
be rejected at the a = 0.01 significance
level.
%3D
(C) If po = 0.38, then the null hypothesis will
be rejected at the a = 0.05 significance
level.
(D) If Po = 0.38, then the null hypothesis will
be rejected at the a= 0.01 significance
level.
(E) If Po = 0.43, then the null hypothesis will
be rejected at the a= 0.05 significance
level.
